Did I order the wrong thing? Confused...

You don't need 600 volt caps in your bass guitar...

 

^mike is right. I am under the impression that they will work though.

 

should work if you can fit it, yep! 25V or 50V will be a lot smaller:

Caps are like people. They come in all shapes and sizes.

Sometimes the difference is because of an actual difference in spec. Capacitors of different capacitance will be different sizes (sometimes). But caps also have a voltage specification, which is essentially a nominal maximum. Those caps are 600v caps, when you could probably get by with less than a tenth of that.

Caps can also be made from different materials, which will have a big impact on their size and shape. A ceramic cap can be very tiny, even at large ratings. But other materials (electrolytic, for example) are much bigger.

And then there's a practical consideration. Sometimes, electrical components are packaged in many different sizes for a given specification. This gives circuit designers some flexibility in terms of choosing a physical size that matches their needs. A .1 uF ceramic cap can be nearly microscopically small, or as large as the caps you're showing.

Caps are also rated by many other factors, but those are the most common reasons why they come in different sizes.

But the good news is, those caps will work great for you. As long as you can fit them in your bass. There are theoretical arguments why you may not want a big package like that for an audio application, but IME they don't translate to the real world with any significance.

 

yup no reason it won't work other than if space is at a premium. electrically, you're fine.

 

I see there are lots of people typing more quickly than me today!

The "or amps" may have been what got you. Some amplifier designs do have very high voltages where the 600v rating would be appropriate.

 

It's also worth noting that literally searching for ".1 cap" might actually get you a part that's very wrong for your application.

Capacitance is rated in farads. One farad is extremely large. Huge. Gigantic. Most audio applications have values that are vastly smaller than that. What you're really looking for is a .1 uF (microfarad) cap. That's a decimal point with six zeros after it before you get to the one.

 

Yep. Most passive systems put out less than 9v.

 

Not all of us typed out "War and Peace".

That was a darn fine post, sir.

 

Yes that part is correct - the 104J code stamped on it means .1 uF. The "10" are the first two numbers in the capacitance rating, and the "4" is the decade, which is basically a multiplier that tells you where the decimal point goes.

 

Since no one has said it yet, I will: there are other film capacitors out there that are A LOT cheaper and do the same thing. Orange Drops were hot in the 60s back when other capacitors were crap. Now pretty much any film capacitor will perform just as good as an Orange Drop

 

That's good. I bought the hype HARD when I was in my early 20s. Sprague had more than a few lunches on me.

 

K is fine. You're not going to even know if the value is off by a few percent.

There's a lot of very serious kool-aid when it comes to capacitors in guitars. I bet most people wouldn't be able to tell the difference between a film capacitor and a ceramic capacitor, much less different brands of film caps. Put something in and see how it sounds. If you don't like it, try something else.
