Panasonic FM 470uF 35V Low-ESR Aluminum Electrolytic Capacitors (12x) Review (2026)

Who these capacitors are for

This pack suits FPV builders who want a reliable, name brand low-ESR capacitor to solder across the power pads of an ESC or power distribution board to smooth voltage spikes and reduce electrical noise that can appear as lines or static in the video feed. Because Panasonic's FM series has a long track record in the hobby specifically for this purpose, it appeals to builders who prefer sourcing a proven part over a cheaper unbranded alternative when noise filtering is the goal. The 12 piece pack size means one order covers several builds or a stock of spares, useful for anyone who assembles or repairs multiple quads over time.

Electrical specifications

According to component datasheets and retailer listings, the Panasonic FM series 470uF 35V capacitor is a radial leaded, polarized aluminum electrolytic type built for ultra low ESR and high ripple current handling relative to standard electrolytic capacitors of the same capacity. Listed ripple current at 100kHz and 105 degrees Celsius is around 1670 to 1790 milliamps depending on the specific datasheet cited, and the part is rated for operation up to 105 degrees Celsius with a stated lifespan of up to 5000 hours at that temperature. Capacitance tolerance is listed at 20 percent, which is standard for this type of component.

Physical size and installation

The individual capacitor measures approximately 10mm in diameter by 20mm in height, with a 5mm lead pitch and 0.6mm lead diameter, dimensions builders should check against available clearance on their frame or stack before ordering. Installation involves soldering the capacitor directly across the positive and negative power pads of an ESC or power distribution board, observing correct polarity since this is a polarized electrolytic type that can be damaged if installed backwards. Builders should also confirm their power system voltage stays safely under the capacitor's 35V rating, accounting for voltage spikes, not just the nominal battery voltage.

Trade-offs and how it compares

Against the same Panasonic FM 470uF 35V capacitor sold in a smaller 4 piece pack, this 12 piece listing offers a lower cost per unit for builders who need several, while the smaller pack suits someone who only needs one or two. Compared with generic uxcell or Fielect branded low-ESR capacitors rated at similar voltage and capacitance, the genuine Panasonic part typically carries a price premium in exchange for tighter manufacturing tolerances and a longer documented track record in FPV specifically. Builders on 6S or higher voltage systems should note the 35V rating here is tighter than some generic alternatives rated at 63V, so higher voltage builds need a different part.

Bottom line

This 12 pack of genuine Panasonic FM 470uF 35V capacitors is a solid choice for builders who want a trusted, well documented low-ESR part for filtering power noise on 2S to roughly 6S FPV builds, with enough units in the pack to cover several projects or replace one across a small fleet of quads. The 35V ceiling means builders on higher voltage systems need to look at a higher rated capacitor instead, and the genuine Panasonic branding costs more than unbranded equivalents with similar published specs on paper. For anyone prioritizing proven reliability and consistent manufacturing quality over the lowest possible price per unit, this pack is a dependable pick.
