FEATURES
•Small size, down to 20 by 16 mils
•Edged trimmed block resistors
•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 × 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.

TYPICAL HIGH FREQUENCY PERFORMANCE ELECTRICAL MODEL
The complex impedance of the chip resistor is given by the
following equations:
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.
This can be seen on the graphs relevant to 02016 (R = 100
Ω
,
LC = 1 x 10
-24
), 0402 (R = 129
Ω
, LC = 15 x 10
-24
) and 1206
(R = 200
Ω
, LC = 100 x 10
-24
).
Note:
The external reactance (Lc and Cg) depends on the PCB material,
the layout and assembly technology. It does affect the HF
performance and needs to be estimated. The external reactance can
be utilized to compensate the internal one.
