Ⅰ.Product overview
The VSTCH1917R automotive-grade common mode choke uses CODACA's self-developed patented technology. Through process innovation, it not only improves electrical performance but also makes soldering between the choke and the PCB simpler and firmer, greatly enhancing the reliability of automotive electronic systems.
The VSTCH1917R series currently offers five models. The inductance range is 220 μH to 1400 μH, the DCR range is 23 mΩ to 45 mΩ, and the product size is 19.5 × 17.0 × 10 mm. Its compact structure makes it suitable for high-density mounting and meets the industry trend toward higher integration and miniaturization in automotive electronics.
Ⅱ.Product features
1.Patented process for high reliability
The VSTCH1917R series uses a precision surface-mount terminal process that keeps coplanarity within 100 μm, greatly improving the bonding accuracy between the choke and the PCB and reducing soldering defects and cold joints. This improves reliability and ensures stable operation of onboard equipment under complex conditions.
Backed by patented technology and an excellent structural design, the choke offers vibration resistance above 5 G, easily handling continuous vibration, shock, and mechanical stress during vehicle operation and building a solid reliability foundation for onboard systems.

2.Compact structure for high-density mounting
As automotive electronics become more integrated, miniaturization and lightweight design of electronic components have become major industry trends. The VSTCH1917R series uses a compact embedded design that integrates the terminal and housing while reducing product height without sacrificing electrical performance, perfectly meeting the needs of high-density mounting.
Compared with traditional common mode chokes, the VSTCH series is smaller and more flexible in layout, significantly saving PCB space in vehicles and helping automakers build more streamlined and integrated automotive electronic control systems.
3.Wide frequency range and high impedance for excellent noise suppression
The VSTCH1917R series features a wide operating frequency range and high impedance, covering high-frequency application scenarios. It precisely and efficiently suppresses common-mode interference in power paths, ensuring stable operation of onboard powertrain systems, multimedia devices, and communication modules, and preventing signal distortion or functional abnormalities caused by noise.
