CH Vishay Sfernice Thin Film Microwave Resistors FEATURES * Small size, down to 20 by 16 mils * Edged trimmed block resistors RoHS COMPLIANT * Pure alumina substrate (99.5 %) * Various terminations: * Pre-tinned over nickel barrier (wraparound or flip chip) for solder reflow * Gold pad for wire (or ribbon) bonding (one face only) * Ohmic range: 10R to 500R * Small internal reactance (LC down to 1 x 10-24) * Tolerance 1 %, 2 %, 5 %, 10 % * TCR: 100 ppm/C in (- 55 C, + 155 C) temperature range Those miniaturized components are designed in such a way that their internal reactance is very small. When correctly mounted and utilized, they function as almost pure resistors on a very large range of frequency, up to 20 GHz.

It does affect the HF performance and needs to be estimated. The external reactance can be utilized to compensate the internal one. f = frequency The resistor is purely resistive when R = (L/C)1/2 = Zo. The smaller the LC product the greater the frequency range over which the resistor looks approximately resistive.
