High Frequency 50 GHz Thin Film Chip Resistor
FEATURES
• Operating frequency 50 GHz
• Thin film microwave resistors
• SMD wraparound or flip chip resistor
• Small size, down to 20 mils by 16 mils
• Edged trimmed block resistors
• Pure alumina substrate (99.5 %)
• Ohmic range: 10R to 500R
• Design kits available
• 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 50 GHz.
• Material categorization: For definitions of compliance

PACKAGING
Standard packaging is waffle pack for sizes 0402 and 0603. Plastic tape and reel (low conductivity) for size 02016.
Plastic tape and reel is available for 0402 and 0603 (low conductivity) or paper tape under request for all sizes.
Depending on the type of terminations, parts will be packed differently:
One face:
• Gold terminations: Active face up
• Tin/silver termination: Active face down
Note
• Please refer to Vishay Sfernice Application Note “Guidelines for Vishay Sfernice Resistive and Inductive Products” for soldering
recommendation (document number 52029, 3. Guidelines for Surface Mounting Components (SMD), profile number 3 applies

PACKAGING RULES
Waffle Pack
Can be filled up to maximum quantity indicated in the table
here above, taking into account the minimum order quantity.
When quantity ordered exceeds maximum quantity of a
single waffle pack, the waffle packs are stacked up on the
top of each other and closed by one single cover. To get
“not stacked up” waffle pack in case of ordered quantity
> maximum number of pieces per package: Please consult
Vishay Sfernice for specific ordering code.
Tape and Reel
Can be filled up to maximum quantity indicated in the table
here above, taking into account the minimum order quantity.
When quantity ordered is between the MOQ and the
maximum reel capacity, only one reel is provided. When
several reels are needed for ordered quantity within MOQ
and maximum reel capacity: Please consult Vishay Sfernice
for specific ordering code.

The chip resistor itself is purely resistive when
R
=
---
. The smaller the L x C product the greater the frequency range over
-
C
which the resistor looks approximately resistive.
Z

This can be seen on the graphs showing the ratio
-------
versus frequency.
R
R, L and C are relevant to the chip resistor itself.
L
c
and C
g
also depends on the way the chip resistor is mounted.
It is important to notice that after assembly the external reactance of L
c
and C
g
will be combined to internal reactance of L and
C. This combination can upgrade or downgrade the HF behaviour of the component.
This is why we are displaying two sets of data:
Z
-
•
-------
versus frequency curves which aims to show at a glance the intrinsic HF performance of a given chip resistor
R
• S-parameters versus frequency curves relevant to chip resistor when assembled on ideal Z0 impedance transmission line
These lines are terminated with adapted source and load impedance respectively Z

and Z
l
