As for Metal Film Fixed Resistor products, it is also to denote the standard PPM as follows:B = 0.1% (15PPM) G = 2% (100PPM) C = 0.25
22、% (25PPM) J = 5% (200PPM) D = 0.5% (50PPM) K = 10% F = 1% (50PPM) Remark: if it it not one of the above standard “tolerance-TCR“, the requirement should be clearly stated when placing order.Example: 1% (25PPM), the 7 thdigit still shows “F” but separately note the requirement of “25PPM” Wattage 1/2
