RCD offers one of the widest ranges of specialty resistors in the industry including microwave resistors and terminations to 26GHz.
If you have a new or existing application and would like assistance selecting the most appropriate resistor model, please complete
the following questions and return via e-mail (engr@rcdcomponents.com) or fax (603-669-5455).
1. DC resistance value:
Tolerance:
2. Please advise quantity level that you'd like quoted (reply required):
Target price:
Is this an existing or new application?
If existing, what parts are you using now? Mfr:
Model:
description
Are there any problems or deficiencies that you’d like RCD to improve upon?(describe)
If a new application, have you found parts made by another firm which are working OK or seem
promising ? If so, please list Mfr:
Model:
description
3. Maximum Operating Frequency:
4. Required impedance (or max % change in value) at max frequency:
5. Preferred Package:
surface mount with solderable terminations,
surface mount with
bondable terminations,
chip with flat tab leads for stripline applications,
cylindrical resistor body
with axial leads,
flange mount,
other (describe):
List preferred (and maximum) package size(s) if applicable:
6. Please advise quantity level to be quoted (reply required):
Target price:
7. What is the power requirement?
Watts at
C
8. If other than standard temp. range of –55ºC to +150ºC, indicate temp. requirement:
9. Are there any surges that the resistor must withstand? If not, go to #10.
a) What is the peak wattage, voltage, or current that a single resistor must withstand during the
surge?
b) What is source of the surge?
Lightning,
Capacitor discharge,
Capacitor Charge,
In-rush current,
ESD, or other (describe):
c) Describe the duration or waveform of the surge (e.g. “Square wave pulse 100mS duration”, “10uS
rise time x 1000uS decay to 50%”, etc.). Be sure to distinguish between mS (milli Sec) and
uS (micro Sec):
d) If a capacitor charge or discharge circuit, list the capacitance value:
e) How often does the surge repeat?
f) How many surges must the parts withstand and what is the stability requirement? e.g. “5% max shift
after 10 pulses”, or “must not open after 100,000 pulses”, or “1% max shift after single pulse” :
g) If the energy (joule) level of the surge is known, please indicate here:
10. If utilized in circuit that is especially sensitive to noise, indicate the max acceptable noise level:
11. Other mandatory requirements:
12. Other desirable requirements:
13. If there are any UL, FCC, Military, Bellcore or other specifications that must be met in addition to the info
provided herein, please indicate the pertinent sections of the spec and send along with this survey form.
14. If relevant, attach schematic diagram/application circuit
