Yellow and grey are used instead of gold and silver because metal particles in the lacquer could affect high-voltage properties. MASS (mg) TYPE VR25, 52 mm 212 VR25, 26 mm 148 OUTLINES The length of the body (L1) is measured by inserting the leads into holes of two identical gauge plates and moving these plates parallel to each other until the resistor body is clamped without deformation (IEC 60294). FUNCTIONAL PERFORMANCE PRODUCT CHARACTERIZATION Standard values of nominal resistance are taken from the E96/E24/E12 series for resistors with a tolerance of ± 1 %, 5 %, or 10 %. The values of the E96/E24/E12 series are in accordance with IEC 60063. LIMITING VALUES LIMITING VOLTAGE (1) Umax.
