ACY SERIES

ACY SERIES

Product catalog summary
Specifications
The document provides specifications for various series of three-phase common-mode choke coils, specifically the ACY31H, ACY37H, and ACY48H series. Key parameters include rated current, inductance, direct current resistance (D.C.R), wire diameter, and dimensions. The inductance measurement condition is set at 10kHz, with a heat resistance grade of Class B (130°C), a rated voltage of 250V AC/DC, dielectric strength voltage of AC2000V for 1 minute, and insulation resistance of over 100MΩ at DC500V.
Features
The choke coils use an amorphous core, providing good anti-pulse attenuation characteristics and excellent stability even in high-temperature environments. They are designed for excellent mounting on boards and are shockproof. The toroidal shape minimizes negative impacts on surrounding components.
Applications
These choke coils are used for noise prevention in various electronic devices.
Impedance Characteristics
The document includes graphs showing impedance characteristics across different frequencies for each series, highlighting their performance in reducing noise.
