Two-stage Single Phase Emi Filter High Efficiency Power Line
Filter
Two-stage Single Phase Filter
YB21D3-6A-Q is the Single Phase Filter with excellent high frequency attenuation performance.The output
can be Fast-on Terminal, Wire, M4 Screw, Or Terminal Block.The
frequency range between 150 KHz and 30 MHz. Compliance with the
limit values required under residential and industrial standards.
Feature Of Power Line Filter:
1. High EMI attenuation: YB22 have designed two-stage filtering, with good differential and
common-mode attenuation.This helps ensure that electronic systems operate with minimal
interference.
2. Low leakage current: YB21D3-6A-Q Emi Filter, rated current 6A,
minimum leakage current 0.4mA, designed with low leakage current to
help reduce power consumption and maximize efficiency.
3. Compact size:The YB-D series EMI filters are designed to be
compact in size, which makes it easy to integrate into electronic
systems with limited space.
Applications Of Single Phase Emi Filter:
-- Electrical and electronic equipment
-- Medical equipment
-- Industrial automation
-- Office automation and datacom equipment
-- Home appliances
