Product catalog summary
Series Specifications
The document outlines specifications for the HVC series of high-value, high-voltage wraparound chip resistors. It includes details on wattage, operating voltage, resistance range, tolerance, temperature coefficient of resistance (TCR), and voltage coefficient of resistance (VCR) for different series types (HVC0805, HVC1206, HVC2512).

Characteristics
Operating temperature range is from -55°C to +155°C. The climatic category is 55/155/56 according to EN 60068-1. Solderability is specified at 250°C for 3 seconds, and the maximum soldering temperature is 260°C for 10 seconds. Long-term stability varies with resistance, with load life and storage conditions affecting stability percentages.

Features
The HVC series features high-value chip resistors in thick film technology, low temperature and voltage dependency, high working voltage up to 3000V, suitability for high vacuum applications, and nickel-barrier/matte tin contact areas.

Terminal Details
The base metal is PtAg with a 100% electroplated matte Sn100 finish. The barrier material is porosity-free Ni with a thickness of 5-8 microns. A baking/annealing process is conducted at 150°C for over 4 hours.

Dimensions and Ordering
Dimensions are provided for different power sizes (0805, 1206, 2512) with specific measurements for length, width, thickness, and terminal dimensions. The ordering information includes tolerance options, resistance values, TCR options, and packaging details.

Standard Part Numbers
A list of standard part numbers is provided for various configurations of the HVC series.
