What are the key features of 7111501?
- 1000 µF capacitance at 50 V DC rating for high-energy bulk storage in power supply stages
- 2000-hour rated service life at maximum rated temperature for long-term reliability
- Radial through-hole package (16 mm × 26 mm) fits standard PCB hole patterns for easy assembly
- Aluminium electrolytic technology provides high capacitance density at low cost per microfarad
- Polarized construction with clearly marked polarity band for correct PCB orientation
What is 7111501 used for?
The RS Pro 7111501 is commonly used in switch-mode power supply output filter stages to reduce voltage ripple, where 1000 µF bulk capacitance smooths the rectified 50 V DC bus to within millivolt ripple specifications. Its 2000-hour lifetime and radial leads make it practical in industrial power adapters, motor-drive intermediate bus capacitor banks, and DC link filters for variable-frequency drives. Audio amplifier power supply rails also benefit from its large capacitance for instantaneous current delivery during peak signal transients.

Frequently Asked Questions
What ripple-current capacity does a 1000 µF 50 V aluminium electrolytic capacitor typically handle in a SMPS filter stage?
A 1000 µF 50 V aluminium electrolytic capacitor in this size class typically handles 1 A to 2 A of rated ripple current at 100 Hz and 120 Hz rectification frequencies, depending on equivalent series resistance and thermal derating. Exceeding the rated ripple current accelerates electrolyte evaporation and reduces the 2000-hour lifetime, so designers should verify the ripple current against the datasheet curve at the operating temperature.
How does the 50 V rating of the RS Pro 7111501 affect its use in a 24 V DC industrial power bus?
With a 50 V rating on a 24 V DC bus, the RS Pro 7111501 operates at 48% of its voltage rating, which is well within the typical 80% derating rule. This margin accommodates up to 40 V DC transients or startup overshoot without risk of dielectric breakdown, making the capacitor suitable for industrial 24 V power rails where load switching can generate voltage spikes of 10 V to 15 V.
What does the 2000-hour lifetime rating mean in practice for an industrial power-supply design?
The 2000-hour rating specifies guaranteed operation at maximum rated voltage and maximum rated temperature — typically 85 °C or 105 °C depending on the series. At lower operating temperatures the lifetime extends approximately by a factor of 2 for every 10 °C reduction; at 65 °C ambient a 2000-hour rated capacitor can realistically deliver 8000 to 16000 hours of service, corresponding to several years in a continuously powered industrial control cabinet.
Can the RS Pro 7111501 be used in audio amplifier power supplies, and what performance should designers expect?
Yes, the 1000 µF value provides substantial bulk energy storage for audio amplifier power rails, capable of supplying approximately 1.25 joules at 50 V — enough to sustain peak output current demands of 10 A for several milliseconds during bass transients. However, aluminium electrolytics have relatively high ESR of 0.1 Ω to 0.5 Ω at audio frequencies, so audiophile designs often parallel them with 10 µF to 100 µF film capacitors to achieve flat impedance response above 10 kHz.
