The MMTSA0050J10400000200 Mylar Capacitor, manufactured by NISSEI, is a 100nF Through Hole, P=5mm RoHS capacitor. It is a type of capacitor that uses a thin printed plastic film as the dielectric instead of a standard paper or mica dielectric. Mylar capacitors are known for their excellent high frequency characteristics, long life, and excellent reliability in harsh environments. They have a wide temperature range from -55°C to +125°C, making them a great choice for demanding electronics applications. This capacitor is a perfect choice for applications that require high frequency and temperature performance.
