- The WMF21 series thermistors feature a radial lead design with a durable resin coating, ensuring low mass and high performance. - Key benefits include effective inrush current limitation, rapid response times, extended service life, and exceptional reliability. - Ideal for various applications such as: - Power supply circuits across all types of power supplies and ballasts/CFLs - Heating loops in CRT-based television sets and monitors - Heating elements in heaters and heating filaments - The thermistors maintain temperature stability while increasing material consistency (B), which results in reduced residual resistance. Their heat capacity allows for more effective inrush current limitation, which is directly related to the thermal time constant (T) and thermal loss constant (d). - WMF21 series thermistors are compatible with a wide range of electronic devices, ensuring versatile use in both residential and industrial applications. - Made from high-quality materials, these thermistors deliver robust performance, making them a reliable choice for engineers and technicians alike.
