Key Features
- 43 mH (43,000 µH) common mode inductance at 50 Hz with 300 mA DC current rating, providing effective EMI attenuation on single-phase AC power lines up to 100 MΩ insulation resistance
- EN-approved vertical-core through-hole structure at 17.5 mm height, enabling compliant single-phase EMI filtering for industrial equipment and home appliances requiring CE marking
- Through-hole box-packed single-phase filter with vertical mount orientation simplifying PCB integration in high-voltage power entry sections where isolation clearance above 10 mm is required
Applications
The PLA10AS4330R3R2B is intended for single-phase AC power line EMI filtering in industrial motor drives, switched-mode power supplies, and home appliance control boards where conducted emissions must comply with EN 55011 or CISPR 22 standards. Its 43 mH inductance and 300 mA current rating make it suitable for low-power appliance input stages, HVAC control units, and building automation gateways requiring a compact through-hole solution with CE-class insulation integrity.

Frequently Asked Questions
What inductance and current rating does PLA10AS4330R3R2B provide, and for which power line frequencies is it optimized?
PLA10AS4330R3R2B provides 43 mH (43,000 µH) of common mode inductance at an operating frequency of 50 Hz with a rated DC current of 300 mA. The 43 mH value is optimized for attenuating conducted EMI on 50 Hz European mains power lines, delivering high impedance to common mode noise in the range of 150 kHz to 30 MHz while passing 50 Hz fundamental current with minimal insertion loss.
How does the 100 MΩ minimum insulation resistance of PLA10AS4330R3R2B contribute to safety compliance in appliance power entry designs?
The 100 MΩ minimum insulation resistance of PLA10AS4330R3R2B ensures leakage current between the windings and core remains below 0.25 µA at 250 VAC, well within the 0.75 mA limit specified by IEC 60335-1 for Class I household appliances. This isolation level supports EN and CE certification for washing machine controllers, dishwasher control boards, and HVAC units where creepage and clearance distances are subject to regulatory audit.
In a switched-mode power supply design, how should PLA10AS4330R3R2B be positioned relative to the rectifier bridge and fuse?
PLA10AS4330R3R2B should be placed on the AC line side between the fuse and the rectifier bridge diodes to intercept common mode noise before it enters the DC bus. Positioning the 43 mH choke within 20 mm of the AC inlet connector and after a 300 mA or higher rated fuse ensures both conducted emission compliance and overcurrent protection. PCB traces carrying up to 300 mA should be at least 0.3 mm wide to handle steady-state current without thermal buildup.
What height clearance does PLA10AS4330R3R2B require on a PCB, and are there smaller alternatives for height-constrained enclosures?
PLA10AS4330R3R2B stands 17.5 mm tall in its vertical-core through-hole configuration, requiring a minimum board-to-enclosure clearance of at least 20 mm. For enclosures with less than 15 mm vertical clearance, designers can evaluate Murata PLA10 series horizontal-mount variants or surface-mount common mode chokes with inductance in the 10 mH to 47 mH range, accepting a trade-off in common mode attenuation of approximately 3 dB to 6 dB compared to the 43 mH vertical type.
