Features: The datasheet emphasizes the resistors’ precision, robust technology, stability under various conditions, pulse load capability, and compliance with industry standards including AEC Q200, RoHS, and REACH.

Ordering and Electrical Specifications

The ordering code for the product series uses an alphanumeric system, ZCM 207 Serie, indicating power rating, tolerance, packaging code, resistance value, TCR (Temperature Coefficient of Resistance), and forming type/various reel diameters.

Performance Characteristics

Electrical specifications provided in the datasheet cover the resistor range, E-Series tolerances, temperature coefficients, working temperature range, permissible film temperature, maximum working voltage, and dielectric withstanding voltage. The resistors can handle a temperature range of -55°C to +155°C and have a nominal power rating up to 1.0W for the ZCM207 and 0.4W for the ZCM204. Various tolerances ranging from ±0.1% to ±5% are available, along with different temperature coefficients tailored to specific applications.

Physical Properties

Physical dimensions, including historical part numbers, are provided for ZCM204 and ZCM207 types, with details on the diameter, pin length and width, and mass. Suggested solder pads dimensions for both wave and reflow soldering techniques are also included. The mass of the ZCM204 type is indicated as 22mg and for the ZCM207 type as 77mg.
