Applications
The DME4P47K-F is commonly deployed in audio crossover networks and signal-coupling circuits where a stable 0.47 µF capacitance is needed to block DC while passing audio-frequency AC signals. Motor run and start circuits use polyester film capacitors of this value range to provide phase-shift capacitance for single-phase induction motors operating at 120 V or 240 V AC. General-purpose timing circuits, RC snubbers across relay contacts, and bypass filters in industrial control equipment also benefit from the low-loss polyester dielectric and convenient through-hole radial format.

Frequently Asked Questions
What capacitance value and tolerance does the DME4P47K-F provide, and how does this affect RC timing circuit accuracy?
The DME4P47K-F has a nominal capacitance of 0.47 µF with a ±10% tolerance, meaning the actual value falls between 0.423 µF and 0.517 µF. In an RC timing circuit with a 100 kΩ resistor targeting a 47 ms time constant (τ = R × C), the ±10% capacitance spread introduces a corresponding ±10% variation in timing, from about 42 ms to 52 ms. Designers requiring tighter than ±5% timing accuracy should specify a tighter-tolerance component, while ±10% is acceptable for relay debounce, audio tone filters, and motor timing applications.
How does a polyester film dielectric in the DME4P47K-F compare to a ceramic capacitor of the same value for audio coupling applications?
Polyester film capacitors exhibit much lower capacitance variation with applied voltage than Class II ceramic capacitors (X7R, X5R), which can lose 30% to 50% of their rated capacitance under DC bias. The DME4P47K-F's 0.47 µF polyester dielectric maintains stable capacitance under signal levels typical of audio circuits, ensuring consistent high-pass corner frequency around 340 Hz when paired with a 1 kΩ source impedance. For audio coupling at frequencies from 20 Hz to 20 kHz, this stability makes film capacitors the preferred choice over ceramic alternatives of the same capacitance value.
In what voltage rating does the DME4P47K-F operate, and is it suitable for 400 V AC motor-run applications?
The DME4P47K-F series from Cornell Dubilier is rated for AC and DC voltage applications typical of its 17 mm body size, with common voltage ratings in the 63 V to 400 V DC range depending on the suffix variant. The 'K' grade in the part number typically indicates a ±10% tolerance capacitor suitable for general-purpose and motor-run use. Confirming the voltage rating from the component datasheet before deploying at 400 V AC is essential, as 400 V AC peak voltage reaches approximately 566 V; a capacitor rated at 630 V DC or 250 V AC would be the minimum safe selection for such a motor-run circuit.
How does the 17 mm body height of the DME4P47K-F influence PCB layout for a consumer electronics design with a 20 mm height clearance?
At 17 mm body height, the DME4P47K-F fits within a 20 mm board clearance with only 3 mm of margin above the component body. The radial lead pitch is typically 5 mm to 7.5 mm, requiring a corresponding pad spacing on the PCB. Designers must also account for a lead-bend radius if the component must be oriented horizontally to reduce effective height, which adds approximately 2 mm to 3 mm to the lead length before bending. For enclosures with less than 15 mm of component clearance, a flat SMD film capacitor in a 1210 or larger case size would be the recommended alternative.
