Single Stage EMI Filter Terminal Block Compact AC Filter
If you’re building equipment that needs clean, stable power input, this is the kind of component that quietly does its job without getting in the way. The CW1D-T is a single-phase, single-stage AC EMI filter with a terminal block (faston/tab) connection — built for panel mounting and designed to fit neatly into the AC input section of your enclosure.
From the label on the unit, you can confirm: CW1D-10A-T, rated at 10A / 115V~250V / 50-60Hz, carrying both CE and RoHS marks. The circuit layout printed on the body shows a classic π-filter topology — CX: 0.1μF, CY: 2×3300pF, L: 2×0.3mH — which tells engineers exactly what they’re working with before they even open a datasheet. That kind of transparency matters when you’re sourcing for production.
The IEC inlet on the front integrates directly with the filter body, so you get the inlet socket and EMI filtering in a single compact unit — no extra wiring between an inlet and a separate filter. Less assembly time, cleaner internal layout, fewer potential failure points.

What This Filter Actually Does — And Where It’s Used
This filter targets conducted EMI on the AC power line — both common mode and differential mode noise. When your equipment switches internally (motor drives, switching power supplies, inverters, industrial controllers), that noise tries to get back onto the mains. This filter stops it at the door.
Typical applications your engineering team will recognize:
- Industrial control panels and PLCs
- Switching power supply modules
- CNC machine tool AC inputs
- Medical device power entry (where leakage current specs allow)
- Test & measurement equipment
- EV charging auxiliary circuits
- LED driver systems and lighting control
- Any equipment requiring CE EMC compliance on the AC input side
The built-in IEC C14 inlet makes this a go-to solution when you want a power entry module + EMI filter in one footprint — extremely common in rack-mount gear, benchtop instruments, and compact industrial enclosures.
Why Buyers Choose This from a Direct Manufacturer
- Integrated design — inlet + filter in one body saves PCB space and panel cutout planning
- Clearly printed circuit values on the label — your engineers can verify specs without chasing a datasheet
- Tab/faston termination speeds up assembly on the production line; no soldering required at connection points
- Dual voltage rating (115V/250V) means one SKU works for both US and European market products
- CE + RoHS certified — satisfies compliance requirements out of the box for most markets
- Current range 1A–10A available across the series — you can standardize on one supplier for multiple product lines
- Direct factory pricing — no distributor markup; MOQ-friendly for both prototype runs and bulk orders
FAQ
Can we get custom current ratings or voltage specs outside the standard range?
Yes. As a manufacturer, we support OEM customization including current rating adjustments, different inlet configurations, and label/marking customization for your brand. Share your target specs and we’ll confirm feasibility with our engineering team directly.
What EMI attenuation performance can we expect, and do you provide insertion loss test data?
We can provide insertion loss curves per CISPR 17 test methodology. For the CW1D-T series, meaningful attenuation starts from around 100kHz and increases significantly through the MHz range — well-suited for SMPS applications targeting EN 55032 / FCC Part 15 Class B compliance. Contact us for the full test report.
What’s the leakage current, and is this filter suitable for medical equipment?
Leakage current is within standard industrial limits. For medical-grade applications (IEC 60601), leakage current requirements are much stricter. We offer medical-grade filter variants separately — please specify your application when inquiring.
What are your MOQ and lead time for bulk orders?
MOQ is flexible depending on model and customization level. Standard catalog models can typically be fulfilled from stock or within short lead times. For large-volume OEM orders, lead time and pricing scale favorably — we recommend sending your forecast so we can give you an accurate quote.
Are these filters compatible with 60Hz North American power grids, and do they meet UL requirements?
The filter is rated for both 50Hz and 60Hz — fully compatible with North American voltage standards at 115V. For UL listing specifically, please contact us to discuss UL-certified variants, as certification scope varies by model. CE certification is standard across the range.
