Best Resistors To Order?

[Love Vintage]

I have been using various brands and types of resistors and would like to start buying extras when I place orders. In reading through Audiokarma and have noticed members using Vishay resistors, are series CCF50, CCF60, & CCF07 the ones I should be looking at to start a small inventory? Or are there others to look at?
Thanks

As a general purpose resistor, I don't see anything wrong with the CCF series, I use the MFR series, slightly better temp coefficient,
happy if someone points out the error I'm making. Specific resistors are needed for flameproof and fusible applications,,,

fusible applications,,,

Yes these normally open up about 2 seconds after a transistor shorts . No seriously, good advice from mbz.

Is the MFR series a Vishay product I can’t seem to find it?

Yageo makes a MFR series. MFR = Metal Film Resistor

LOL!

Yes Yageo, bit sloppy on my part.

Interesting. So do fuses.

Here is a comparison chart I built myself to help select the best resistors for each application:

Metal Film Resistor Choices

Vishay


CMF: very low noise, 2% precision, 250 mW


RN/RL: very low noise, 1% precision, 250 Mw


SFR – standard metal film resistors




5073 or “PRO” series – metal film resistors for power handling




CMF – industrial metal film resistors – precision, flame retardant



RN and RL (Military CMF) - industrial metal film resistors – precision, flame retardant



CCF – industrial metal film resistors – power, flameproof



CPF – industrial metal film resistors – power, precision, flameproof



PTF – high precision metal film resistors



Xicon
270-271-273 MF-RC metal film series


Price comparison
1K resistor lowest wattage & price at or above 250mW in each series
· Vishay CCF 250mW $0.10 or $0.04/100

· Vishay SFR 250mW $0.10 or $0.04/100 (low end standard)

· Vishay RN 250mW $0.13 or $0.11/100 (mil-grade low noise, precision industrial)

· Vishay CMF 500mW $0.14 or $0.11/100 (standard-grade, low noise, precision industrial)

· Xicon MF-RC 250mW $0.17

· Vishay PRO 2W $0.34 or $0.19/100 (higher power but standard grade)

· Vishay CPF 1W $0.49 or $0.28/100 (high power flameproof)

· Vishay PPF 1W $0.49 or $0.40/100 (higher power precision)

· Vishay PTF 250mW $1.83 or $1.41/100 (high precision)


When I build my inventory, I choose CMF in 100 piece quantities. They are low noise and most all of what I do is audio path.

When I'm buying 1-2 each, I get either RN of CMF... again because I'm mostly dealing with audio path.

For applications where required wattage is 2 or more watts, I use CPF.

Vishay also has non-magnetics for critical signal path and feedback locations.

I've never seen that family. Thanks!

Wow great information, seems like you guys prefer Vishay to Yageo, is there a reason in particular?
