Polymer fuses

Fusibles de polímero o fusibles rearmables - son componentes que protegen tu circuito contra las sobrecargas. Es un invento ingenio - por la carácteristica de polímero su resistencia se aumenta con la temperatura que corresponde a la corriente que fluye trás un circuito. Así que en principio fusibles de polímero funccionan en una forma muy parecida a termistores. Para saber más sobre las diferencias consulta nuestro foro y sección de tutoriales. Los parametros que especifican funccionamiento de fusibles son la intensidad y tensión de funccionamiento. De nuevo, saber requerimientos para estos parametros es crucial para no dañar tu circuito. En nuestra oferta tenemos fusible desde 60 hasta 90V de tensión y desde 100mA hasta 900mA de intensidad
