Product Overview

AVX SA305C334MAA is a 0.33 uF, 50 V DC axial multilayer ceramic capacitor from the SpinGuard SA series, in the SA30 case size. The dielectric is X7R and the tolerance is +/-20 %, the M in the number. The ceramic chip sits inside a conformal coating with a wire lead out of each end, so it mounts through-hole on a board or spans two points on a terminal strip.

Key Features

• Capacitance: 0.33 uF (330 nF, 330,000 pF), marked 334
• Rated voltage: 50 V DC (the 5 in the number)
• Dielectric: X7R (the C in the number)
• Tolerance: +/-20 % (M)
• SA30 case: 7.37 mm long, 3.81 mm diameter, 0.445 mm leads
• Lead code A: standard solderable leads, not the RoHS version
• Non-polar: installs either way round

Applications

• Input bypass on a three-terminal linear regulator, where 0.33 uF is the value the classic schematic calls for
• Supply decoupling beside through-hole logic and op amp packages on older boards
• Point-to-point repairs on terminal strips, where axial leads reach both lugs without extra wire
• Breadboard and prototype bypass networks for builders and hobbyists

Frequently Asked Questions

What does the 334 on the body mean?

It is the standard three-digit capacitance code: 33 followed by four zeros in picofarads, so 330,000 pF, which is 330 nF or 0.33 uF.

Does it matter which way round it goes in?

No. A ceramic capacitor is non-polar, so either lead can go to either pad.

My parts list calls for SA305C334KAR. Will this one stand in?

That number is the same SA30 case, 50 V, X7R and 0.33 uF. It differs in two letters: K is +/-10 % tolerance where this part's M is +/-20 %, and R marks RoHS-compliant leads. Where the circuit can live with the wider tolerance and non-RoHS leads, the footprint and value match.

More pieces cost less each - the price-break table on this page shows what each quantity costs.

Multilayer ceramic stacks mostly live on surface-mount boards now; this one keeps a wire at each end under its yellow coat, for the boards that still take through-hole parts. Bend the leads to your hole spacing and solder it in.
