(SPIDER Automation) YHDC LN212-1.2 Common Mode Choke | 250V, PCB Mount | EMI/Common Mode Interference Suppression

SPIDER Automation YHDC LN212-1.2 Common Mode Choke | 250V PCB-Mount EMI Suppression | For Switching Power Supplies

Description

The YHDC LN212-1.2 Common Mode Choke is an electromagnetic interference suppression component designed for use in switching power supplies and other compatible electronic circuits where common-mode interference needs to be controlled. The choke is intended to help suppress unwanted common-mode noise signals while allowing the intended power signal to pass through the circuit.

The component is designed for PCB installation, making it suitable for integration directly onto printed circuit boards used in power supplies and electronic equipment. It has a specified 250V operating voltage and uses a housing/material system with UL94-V0 flame resistance.

The LN212-1.2 is specified for an operating and storage temperature range of -20°C to +100°C. Its insulation performance includes a dielectric strength of 1.5kV for 1 minute between the two coils and 4kV for 1 minute between the coil and shell.

The component also specifies an inrush current capability of 20 times the rated current for 10ms. This characteristic is relevant in switching power supply designs where short-duration startup or transient currents can occur.
