CTX300-4 Coupled Inductor For Power Conversion

CTX300-4 is intended for power conversion stages that need a higher inductance value in a through-hole toroid form. The part is specified as 300 µH nominal inductance with ±10% tolerance, supporting designs like filtering chokes and lower-frequency energy storage. CTX300-4 is rated for 1.2 A DC current and lists a 0.36 Ω max DCR, which helps estimate copper loss under load. The series is commonly used in switching regulators and EMI filtering where a toroidal core helps keep magnetic fields contained relative to rod-core approaches. Use CTX300-4 when you want a stable inductance value in a serviceable, leaded package and can accommodate the toroid footprint. Request a quote for CTX300-4.
