Custom EMI Filter Single Phase ODM Power Line Solutions

The CW4L2-S(005) Series is a custom-configured single phase AC power line EMI filter developed under LXLZ’s ODM engineering program — designed for buyers who require performance specifications, physical dimensions, or certification configurations beyond what standard catalog products can deliver.

Manufactured by LXLZ (Shenzhen Lize Electronics), the (005) suffix in the model designation identifies this unit as a factory-customized variant — produced to a specific engineering specification developed in collaboration with an OEM customer. This series demonstrates our capability to engineer, validate, and manufacture EMI filters to precise customer-defined requirements while maintaining full CE and RoHS certification compliance.

With a reinforced wide-body nickel-plated steel housing, gold-plated terminal block connections with transparent safety covers, and an extended current range of 1A to 40A at 115VAC / 250VAC, 50Hz / 60Hz, the CW4L2-S(005) series is engineered for demanding industrial, commercial, and OEM integration applications where standard product dimensions and specifications fall short.

This product page also serves as a direct demonstration to prospective B2B buyers: if you have a custom EMI filter requirement, we have the engineering infrastructure to deliver it.

What the (005) Designation Means

The suffix (005) in the model number CW4L2-10A-S(005) is not a standard catalog code — it is an ODM project identifier assigned during the customer engineering collaboration process.

This designation indicates:

Customer-Specified Engineering Modifications

The (005) variant incorporates one or more engineering parameters defined by a specific customer requirement — which may include:

• Modified inductance value (4×0.7mH — distinct from standard catalog L values)
• Enlarged housing body for higher thermal dissipation at extended current ratings
• 4-point wide mounting flange for enhanced mechanical stability
• Modified terminal block configuration (3-position LOAD block vs. standard 2-position)
• Customized internal component selection for specific insertion loss targets

What This Means for New ODM Buyers

Every OEM/ODM project at LXLZ follows the same structured development process:

1. Requirement Definition
   → Current rating, voltage, frequency, insertion loss targets,
     physical dimensions, mounting requirements, certifications

2. Engineering Review & Proposal
   → Circuit design, component selection, housing specification,
     cost estimate, lead time confirmation

3. Prototype Development
   → Sample units produced to agreed specification

4. Customer Validation
   → Electrical testing, EMC pre-compliance, mechanical fit verification

5. Production Release
   → Mass production with full QC documentation

6. Ongoing Supply
   → Stable production supply with dedicated model code

Whether your requirement is a minor parameter adjustment or a fully custom filter design, our engineering team has the capability and process to support your program from specification through production.

Circuit & Internal Component Details

Capacitor Network

• CX (X-Class, Differential-Mode): 3 × 0.1μF Line-to-line differential-mode suppression capacitors — attenuate noise generated by switching power supplies, inverter loads, and non-linear current-drawing equipment
• CY (Y-Class, Common-Mode): 2 × 3300pF Line-to-earth and neutral-to-earth common-mode suppression — provide a low-impedance path to chassis ground for high-frequency common-mode interference currents

Inductor Network

• L: 4 × 0.7mH Common-Mode Choke (Custom inductance value — engineered between the 0.5mH standard light-duty and 0.8mH heavy-duty values, optimized for the specific insertion loss and current thermal profile of this ODM specification) High-permeability toroidal core construction — high impedance to interference frequencies, negligible impedance at 50/60Hz fundamental

Bleed Resistor

• R: 1MΩ / 0.5W X-capacitor safety discharge path — ensures stored charge dissipation within safety-standard required timeframe after AC power disconnection. Mandatory for IEC 60335 and EN 60950 compliance

Product Features

Reinforced Wide-Body Nickel-Plated Steel Housing

The enlarged housing body of the S(005) series compared to standard CW4L2 variants provides:

• Increased internal volume for higher-rated component assemblies at 30A–40A current levels
• Enhanced thermal dissipation area for sustained full-load operation
• Superior electromagnetic shielding effectiveness — fully enclosed construction with no aperture leakage
• Robust mechanical integrity for industrial panel and chassis mounting
• Reliable chassis ground bonding surface for common-mode noise attenuation

4-Point Wide Mounting Flange

• Four-point screw fixing pattern on an extended mounting base provides significantly greater mechanical stability compared to standard 2-point mounting ear designs
• Prevents filter body rotation or movement under cable pull forces and vibration loads
• Wider flange footprint distributes mounting stress across a larger panel area — suitable for heavy-gauge cable installations at high current ratings

Gold-Plated Terminal Blocks with Transparent Safety Covers

• 3-position terminal blocks on both LINE and LOAD sides — accommodating L, N, and E on both input and output, enabling full earth continuity through the filter
• Gold-plated copper terminals — minimal contact resistance, oxidation resistance, long-term current-carrying reliability
• Transparent protective terminal covers — operator safety, contamination protection, and compliance with industrial enclosure safety requirements
• Clear LINE / LOAD directional labeling eliminates installation polarity errors

Extended Current Range: 1A to 40A

The S(005) housing and component specification supports the full current range from 1A to 40A within a single product platform — providing procurement teams with a single-source, single-form-factor EMI filter solution across a wide range of equipment power ratings

Dual Voltage: 115VAC / 250VAC

Compatible with both North American and international power standards — a single product variant serves global OEM programs without region-specific inventory variants
