MAL216259472E3 Overview
An aluminum electrolytic capacitor is a polarized passive component that uses an etched aluminum foil anode, a paper separator impregnated with liquid electrolyte, and a cathode foil to form a high-capacitance-per-volume energy storage device. Within the passive component taxonomy it falls under electrolytic capacitors -> capacitors -> passive components, and is generally used for bulk energy storage, DC link filtering, and power-rail smoothing where very high µF values are needed at low cost. The 162 series is purpose-built for switch-mode power supplies, motor drives, and UPS input/output filtering where 100 V to 450 V rails are common.
Key features of the MAL216259472E3 include a 20 % capacitance tolerance, an operating temperature range of -40 °C to +105 °C, and a ripple current capability appropriate for the 162 RHS high-ripple series. The snap-in termination provides reliable through-hole mounting with mechanical retention suitable for chassis-mounted and PCB-mounted power sections. Its 4700 µF bulk reservoir is sufficient to hold up a 100 V rail during brief load transients or mains dropouts.
Architecturally, the device combines an etched anode foil that maximizes surface area for the dielectric aluminum-oxide layer, a cathode foil, and a borax-based electrolyte absorbed in the separator paper. Compared to solid polymer or film capacitors, the wet electrolytic construction delivers far higher µF/volume at the expense of higher ESR and shorter lifetime, which is acceptable in 105 °C-rated bulk filtering roles.
Typical applications include industrial switch-mode power supplies (SMPS), 3-phase input rectifiers and DC link filtering, motor drives, UPS systems, solar inverters, and welding equipment. The 100 V rating aligns with 48 V telecom rails after rectification, 72 V battery stacks, and 3-phase rectified 400 V systems stepped down by intermediate rails.
When designing with this part, observe the 5-minute re-voltage procedure for unused capacitors stored more than 6 months, respect the 5 mm clearance around the pressure relief vent, and ensure the 38 mΩ ESR is compatible with the ripple budget. A 1 A/µs dV/dt limit applies; do not place the part directly across a fast-switching node without a damping network.

Typical Applications
MAL216259472E3 is suitable for 6 applications: Industrial Switch-Mode Power Supply (SMPS) Bulk Filtering, DC Link Filtering in Variable-Frequency Drives (VFD), Uninterruptible Power Supply (UPS) Output Filter, Solar Inverter Low-Voltage Bus Smoothing, Welding Equipment Output Smoothing, Industrial Motor Soft-Start Energy Buffer.
Industrial Switch-Mode Power Supply (SMPS) Bulk Filtering
The Vishay MAL216259472E3 fits the 100 V bulk capacitor position of a 3-phase-input industrial SMPS after the bridge rectifier and PFC stage. Its 4700 µF reservoir maintains the DC rail during the AC line half-cycle trough, sustaining a hold-up time of typically 20 ms when paired with a 1 kW load. The 38 mΩ ESR at 100 Hz keeps the 120 Hz ripple component below 5 % of the nominal rail, while the 105 °C rating tolerates the heat soak inside a sealed converter chassis. Designers use the snap-in 12.7 mm pitch footprint to mount the part directly on the power PCB next to the boost inductor, reducing lead inductance versus axial alternatives.
Recommended
DC Link Filtering in Variable-Frequency Drives (VFD)
The MAL216259472E3 is well-suited as the DC link capacitor in a low-voltage variable-frequency drive operating on a rectified 100 V bus. The 4700 µF capacitance absorbs regenerative energy from the motor during deceleration, protecting the IGBT inverter from over-voltage transients. The 38 mΩ ESR dissipates the high-frequency switching ripple from 4-16 kHz IGBT bridges, while the 5000 h / 105 °C load life ensures years of service in industrial cabinet environments. Mount vertically on the heatsink side of the drive chassis using the snap-in tabs for mechanical retention.
Recommended
Uninterruptible Power Supply (UPS) Output Filter
In a 100 V output UPS, the Vishay MAL216259472E3 filters the inverter output before the output transformer or filter inductor, smoothing the PWM waveform into a clean DC rail for telecom equipment or industrial DC loads. The 4700 µF bulk capacitance handles step-load transients up to 100 A peak, while the 38 mΩ ESR limits the 120 Hz ripple from the line-frequency inverter stage. The 162 RHS series is rated for continuous 105 °C operation, well above the typical 65-75 °C operating point inside a UPS cabinet, extending the capacitor's effective lifetime to 50 000+ hours in this application.
Recommended
Solar Inverter Low-Voltage Bus Smoothing
The MAL216259472E3 serves in the low-voltage intermediate bus of a solar micro-inverter or string inverter, between the boost PFC stage and the H-bridge output. With MPPT ripple frequencies of 5-20 kHz, the 38 mΩ ESR and 4700 µF bulk capacitance maintain bus regulation during irradiance steps (cloud edges). The 105 °C rating handles the rooftop thermal environment, while the snap-in 12.7 mm pitch enables automated assembly. Note that for direct 600 V PV strings, choose a higher-voltage 162-series part; the MAL216259472E3 is intended for the post-PFC 100 V rail, not the PV input.
Recommended
Welding Equipment Output Smoothing
Inverter-based welding machines use large bulk capacitors on the rectified mains or output stage to store energy for the welding arc and to smooth the high-current pulses. The MAL216259472E3's 4700 µF / 100 V rating suits the lower-voltage DC bus of a 100 V-class welder, with the 38 mΩ ESR handling the arc-current ripple (often 100-300 A peak). The 105 °C rating tolerates the harsh thermal environment near the welding transformer, and the 5000 h load life is sufficient for the duty cycle of professional welding equipment. Mount with adequate clearance around the pressure relief vent for safety.
Recommended
Industrial Motor Soft-Start Energy Buffer
Motor soft-start circuits store energy in a bulk capacitor to provide a controlled ramp-up current to large inductive loads. The Vishay MAL216259472E3 with its 4700 µF capacitance supplies the energy required to start 5-10 HP industrial motors from a 100 V DC bus, while the 38 mΩ ESR limits inrush heating. The snap-in mechanical retention handles the vibration environment of motor cabinets, and the 105 °C rating tolerates the enclosed back-of-cabinet ambient. The 5000 h lifetime matches the typical motor control electronics refresh cycle of 5-7 years in factory automation.

Design Notes
Estimated: at 105 °C ambient and full-rated ripple current, the MAL216259472E3 reaches a junction temperature where electrolyte evaporation accelerates. For each 10 °C reduction below 105 °C, lifetime doubles (Arrhenius rule). At a typical 75 °C cabinet hotspot, expect >20 000 h service life. Provide at least 5 mm clearance around the pressure relief vent and ensure the snap-in tabs make solid thermal contact with the PCB copper for heat-sinking.
Capacitors stored for more than 6 months without voltage applied may need re-aging: apply rated voltage through a 1 kΩ current-limiting resistor for 5 minutes before installation. Reversed polarity will destroy the part within seconds - the longer lead and sleeve stripe mark the positive anode. Do not exceed 1 A/µs dV/dt; place a damping resistor or inductor in series with fast-switching nodes. Snap-in mounting holes should be 6.3 mm to avoid stress on the terminals.
Place the MAL216259472E3 as close as possible to the rectifier output and the PFC stage input to minimize high-frequency loop inductance. Use wide copper pours (>=2 oz) on the positive and negative terminals to handle the high ripple current. Keep at least 10 mm separation between the capacitor can and adjacent heat sources (transformers, MOSFETs). The pressure relief vent on top must point away from any sensitive circuitry or plastic enclosures.
