IEC Inlet Filter with Fuse Socket EMI Filter 115/250V
Table of Contents
If you’re building equipment that needs to stay clean on the power line — whether it’s medical devices, industrial controls, lab instruments, or telecom hardware — you already know how much a reliable EMI filter matters. This isn’t just a passive component; it’s the first line of defense between your equipment and whatever garbage is riding on the mains.
Our CW2A Series IEC Inlet EMI Filter combines a standard IEC C14 inlet socket, a built-in fuse holder, and a single-stage EMI filter into one compact, panel-mount unit. Everything your engineers need at the power entry point, already integrated — no extra hardware, no messy wiring workarounds.
What You’re Actually Getting (Image Analysis + Specs)
From the unit itself, you can see it’s a metal-shielded housing — not the cheap plastic-bodied stuff that floods the market. The label clearly shows:
- Model: CW2A-10A-T(001)
- Voltage: 115V / 250V
- Frequency: 50/60Hz
- Current Rating: 10A
- Inductance: L: 2×0.3mH
- Capacitors: CX: 0.1μF (×2), CY: 2×3300pF (Y2)
- Flame Rating: UL94V-0 (on the plastic components)
- Certifications: CE, ROHS compliant
The IEC C14 socket face (black, panel-mount style) includes a dual fuse drawer — the kind engineers actually prefer because fuse replacement takes seconds without tools or opening the enclosure.
Key Features & Benefits
| Feature | What It Means for Your Production |
|---|---|
| IEC C14 inlet + fuse + EMI filter in one body | Reduces BOM complexity, saves PCB/panel space, faster assembly |
| Single-stage LC filter topology | Effective attenuation on both common mode and differential mode noise |
| Metal housing with grounding tab | Better shielding integrity, direct chassis ground connection |
| 115V/250V dual voltage rated | One SKU covers both North American and international market equipment |
| 1A–10A current range (series) | Flexible across product lines — from low-power instrumentation to heavier loads |
| UL94V-0 flame-rated housing material | Meets fire safety requirements for embedded/enclosed equipment |
| CE + RoHS compliant | Clears the paperwork hurdle for EU market entry |
| Panel-mount screw design | Secure, vibration-resistant mounting — suits industrial and transport environments |
Typical Applications
This filter fits right into the power entry section of:
- Industrial control panels and PLC enclosures
- Medical equipment (lab analyzers, diagnostic devices — check leakage current specs with your compliance team)
- Test & measurement instruments
- Telecom and networking equipment
- Frequency inverters / motor drives
- Power supplies and UPS systems
- AV and broadcast equipment
Basically, any equipment where conducted EMI emissions need to stay within CISPR 22 / EN 55032 limits, or where incoming line noise could destabilize sensitive circuits.
Manufacturing Advantage — Why Source Direct from Us
We’re not a trading company. We manufacture these in-house, which means:
- Consistent component specs — we control inductor winding, capacitor sourcing, and housing production. You’re not getting random substitutions batch to batch.
- Custom current ratings on request — need 1A, 3A, 6A, or something specific to your product line? We can configure it.
- Private labeling / OEM available — your brand on the label, your part number in our system.
- Traceability — each production batch carries documentation for quality audits and compliance reviews.
- Competitive MOQ — we work with B2B buyers on volume pricing from moderate quantities upward. No retail markups.
- Pre-shipment testing — insertion loss, withstand voltage (Hi-Pot), and leakage current are tested before shipment.

Best Practices — From the Field
A few things that come up repeatedly when engineers integrate this type of filter:
- Mount it as close to the panel entry point as possible. The longer the unfiltered wire runs inside the enclosure, the more you’re radiating internally before the filter even does its job.
- Make sure your chassis ground connection is solid. The grounding tab on the metal housing needs a low-impedance path to chassis ground — a loose or painted surface under the tab kills your common-mode attenuation.
- Don’t run filtered and unfiltered wires in the same harness. Capacitive coupling between them will bypass the filter. Keep them physically separated.
- Match the fuse rating to your actual inrush and steady-state current — don’t just max it out. Oversized fuses defeat the protection purpose.
- For medical applications, verify leakage current independently. Y-capacitor values affect touch current — your compliance engineer will want to review this before final design sign-off.
FAQ
Can you supply different current ratings within the CW2A series, and what’s the MOQ for each?
Yes. The CW2A series covers 1A through 10A configurations. MOQ and pricing vary by current rating and total order volume. We recommend sharing your annual forecast so we can give you tiered pricing that actually reflects your purchasing scale. Send us your target specs and quantities — we’ll quote within 24 hours.
Do these carry CE certification, and can you provide the full test report?
The units are CE marked and RoHS compliant as shown on the label. We can provide the Declaration of Conformity and relevant test reports upon request. If you need specific insertion loss curves (typically tested per CISPR 17) for your internal documentation, let us know — we can share available data or discuss custom testing arrangements for large orders.
Can we get OEM labeling with our own brand or part number?
Absolutely. OEM and private label are part of what we do for B2B customers. Custom printing on the label, custom part number coding, and even packaging customization are available. There’s typically a minimum order threshold for OEM runs — reach out and we’ll work out the details based on your volume.
What’s the lead time for bulk orders, and how do you handle quality consistency across batches?
Standard stock items typically ship within 5–15 business days depending on quantity. For larger or custom orders, lead times range from 3–6 weeks. Batch-to-batch consistency is maintained through in-house component control and our pre-shipment inspection process. We can provide batch test records and retain samples if required for your supplier qualification process.
Are these suitable for medical device applications, and what leakage current can we expect?
The CW2A series is used in equipment adjacent to medical environments, but formal medical-grade classification (IEC 60601 compliance) depends on your specific application and leakage current requirements. The Y-capacitor configuration in this unit will contribute to earth leakage current. We recommend consulting with your compliance team and can provide component datasheets to support your analysis. For stricter medical leakage specs, we also offer filter configurations with reduced Y-cap values — ask about medical-grade variants.
