NPO: Temperature compensation type, have little or no change in capacitance with variation in temperature.
X7R: Temperature stable type for by-pass and decoupling in radio and television receivers, computers servo system.
Z5U/Y5V: General type by-pass and filtering applications.
Metal Film Box Resistors are constructed with metalized polyester film dielectric, copperply lead, encapsulated in plastic case with epoxy resin sealed. They are suitable for filtering, bypass, decoupling, coupling blocking, timing circuit and ideal for use in data processing, telecommunication equipments, and industrial automatic control systems.
