Thin Film Microwave Resistors
FEATURES
• Small size, down to 20 by 16 mils
0402 (P)
• Edged trimmed block resistors
• Pure alumina substrate (99.5%)
• Various terminations:
02016 (P)
• Pre-tinned over Nickel Barrier (wraparound or flip chip)
for solder reflow
• Gold pad for wire (or ribbon) bonding
• Ohmic range: 10R to 500R
• Small internal reactance (LC down to 1 x 10- 24
)
• Tolerance 1%, 5%, 10%,
0402 (B)
• TCR: 100ppm/°C
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 20GHz.

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.
The complex impedance of the chip resistor is given by the
following equations:
1 + j XL/R
1 + j R/XC
Z = R
with XL = 2πfL: Reactance of the
internal inductance
This can be seen on the graphs relevant to 02016 (R =100Ω,
LC = 1 x 10- 24), 0402 (R = 129Ω, LC = 15 x 10- 24) and 1206
(R = 200Ω, LC = 100 x 10- 24).
XL (XC + XL) + R2
θ= Arc tg
with Xc= I/2πfC: Reactance of the
internal capacitance
R XC
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.
