CM SERIES

Product catalog summary

Overview: The document provides technical specifications and features of various series of common-mode choke coils, including CMT, CMB, and CMS series. These components are used to suppress electromagnetic interference in electronic circuits.

Specifications:

CMT Series: Includes models like CMT19V and CMT25V/H. Key parameters include rated current, inductance, DC resistance, wire diameter, and dimensions. The inductance is measured at 10kHz, with an insulation class of E (120°C), rated voltage of 250V AC/DC, and dielectric strength of AC2000V for 1 minute.
CMB Series: Models include CMB19V and CMB25V. Specifications cover rated current, inductance, DC resistance, wire diameter, dimensions, and pin pitch. Similar measurement conditions and insulation specifications as the CMT series apply.
CMS Series: Models like CMS12V are highlighted. Specifications include rated current, inductance, DC resistance, wire diameter, and dimensions. The series is noted for its small size and lightweight due to high permeability cores.

Features:

All series feature excellent mounting on boards, shock resistance, low temperature rise, and a toroidal shape that minimizes impact on surrounding components.
The CMS series is particularly noted for its compact and lightweight design.

Impedance Characteristics: Graphs and tables illustrate the impedance characteristics across different frequencies for each series, highlighting their performance in suppressing interference.

Compliance: All products are RoHS compliant, ensuring they meet environmental and safety standards.
