AL213639229E3 - 22µF 100V Aluminum Electrolytic Capacitor | Vishay
MPN: AL213639229E3 ✓ Hoạt độngAL213639229E3 Tóm tắt
An aluminum electrolytic capacitor (Al e-cap) is a polarized passive component that uses an anodized aluminum oxide dielectric layer and a non-solid electrolyte to store charge. Al e-caps occupy the entry-level tier of the electrolytic capacitor family, sit below tantalum and polymer capacitors in the dielectric-quality hierarchy, and dominate bulk energy storage and decoupling roles in power management, motor drive, and audio circuits where cost-per-microfarad matters more than absolute precision.
Key specifications of the AL213639229E3 include 22µF nominal capacitance (20% tolerance), 100V DC rated voltage, 4000 hours rated life at 105°C, low impedance / low ESR, and excellent ripple current capability. The device is charge- and discharge-proof, and its insulated radial leads simplify through-hole PCB insertion and wave soldering. Operating temperature range spans -40°C to +105°C.
Internally the device combines a high-purity aluminum foil anode with a manganese-oxide non-solid electrolyte and a cathode foil separated by separator paper wound into a cylindrical jelly-roll. The pressure relief vent in the base prevents catastrophic failure under reverse-bias, over-voltage, or end-of-life conditions, an essential safety feature for service engineers.
Typical applications for the AL213639229E3 include SMPS output filtering, DC/DC converter input/output smoothing, industrial inverter bus filtering, audio amplifier power supply bypassing, motor driver energy reservoirs, and general-purpose bulk decoupling on 48V-100V rails. It pairs naturally with the MAL2136 family siblings for higher-voltage or higher-capacitance rails.
Designers should pay attention to the polarity marking on the sleeve and observe the recommended ripple current derating above 60°C ambient. For designs exceeding 4000 hours at +105°C, consider the larger-case 10,000-hour variants of the MAL2136 family, which share the same series heritage and reliability profile.

Ứng dụng tiêu biểu
AL213639229E3 phù hợp cho 6 Áp dụngs: SMPS Output Bulk Filtering, DC/DC Converter Input Smoothing, Industrial Motor Drive Bus Capacitors, Audio Amplifier Power Supply Bypass, Industrial 48V Telecom Rectifier Filtering, General-Purpose Bulk Decoupling on 100V Rails.
SMPS Output Bulk Filtering
The AL213639229E3 is a strong fit for SMPS output bulk filtering on 48-100V rails because its 22µF/100V rating and low ESR directly reduce output ripple while its 4000-hour life at +105°C matches typical SMPS thermal stress. Per the MAL2136 datasheet, this series is explicitly designed for switched-mode power supply output stages, providing the bulk reservoir that absorbs high-frequency switching ripple and load transients. Placed across the output rectifier with low-ESR ceramic or polymer caps in parallel, the AL213639229E3 handles the bulk energy storage and DC bias while the smaller ceramics bypass high-frequency noise. Compared to general-purpose Al e-caps without the 4000-hour rating, this Vishay part adds 2x the operating life, reducing field-return rates in industrial-grade supplies.

DC/DC Converter Input Smoothing
The AL213639229E3 fits DC/DC converter input-smoothing roles where 100V-rated bulk capacitance handles transient back-EMF and input ripple from upstream rectification stages. Its 22µF value is well-sized for 24V-72V intermediate bus inputs to isolated or non-isolated DC/DC modules, while the low impedance characteristic minimizes AC losses at the converter's switching frequency. The MAL2136 series datasheet specifies this part for DC/DC converters, and the 4000-hour life at +105°C aligns with typical converter ambient temperatures. Designers typically place one or two AL213639229E3 caps at the converter input, in parallel with a smaller ceramic to handle switching-frequency bypass.

Industrial Motor Drive Bus Capacitors
The AL213639229E3 is suited for industrial motor drive bus filtering on 60V-100V rectified mains, providing local bulk energy for inverter switching transients and regenerative braking absorption. Per the MAL2136 series datasheet, the part's charge- and discharge-proof construction handles repetitive inrush from PWM switching and braking energy return. The 4000-hour life at +105°C suits enclosed industrial drives with elevated ambient temperatures, and the pressure-relief vent provides safe failure mode under end-of-life or over-voltage events. Placed across the DC bus of small VFDs or BLDC drives, the AL213639229E3 works alongside film capacitors for high-frequency switching noise attenuation.

Audio Amplifier Power Supply Bypass
The AL213639229E3 provides bulk capacitance for ±50V or single-ended 100V audio amplifier power supplies, where its 22µF/100V rating complements the energy reservoir that smooths the rectified mains and feeds the amplifier's power stage. The MAL2136 series low-impedance characteristic reduces power supply-induced distortion in audio amplifiers compared to general-purpose Al e-caps, and the 4000-hour life supports long-life hi-fi and pro-audio designs. Place one AL213639229E3 per amplifier channel on the power supply rail alongside a small film bypass cap for best noise performance. The polarized construction requires correct orientation matching the rectifier polarity marking.

Industrial 48V Telecom Rectifier Filtering
The AL213639229E3 fits 48V telecom rectifier bulk filtering where its 100V rating provides 2x safety margin over 48V working voltage, extending capacitor life and reducing field failures. The 22µF value is well-matched to local bulk filtering on secondary distribution boards and PoE+ applications where 56V rails are common. Per the MAL2136 series datasheet, this part's 4000-hour life at +105°C suits the 24/7 operating demands of telecom infrastructure. Pair with smaller-value ceramics or films for high-frequency switching bypass, and observe polarity during PCB assembly.

General-Purpose Bulk Decoupling on 100V Rails
The AL213639229E3 is a general-purpose bulk decoupling choice for 100V rails in industrial control, instrumentation, and test equipment where its 22µF/100V rating handles local energy storage and supply-line decoupling. The MAL2136 series is specified for general-purpose power applications and the 4000-hour life at +105°C fits commercial/industrial operating profiles. The radial through-hole package simplifies wave soldering and hand-prototyping, and the blue PET sleeve provides electrical insulation. Pair with smaller MLCC bypass caps for high-frequency noise attenuation, and observe ripple current derating above 60°C ambient per the datasheet.

Ghi chú thiết kế
Estimated: At +105°C ambient full-rated ripple current, the AL213639229E3 reaches its 4000-hour end-of-life per the MAL2136 series Arrhenius derating curve. For designs exceeding 60°C ambient, ripple current must be reduced per the datasheet derating table, typically to 50% at +95°C. Mount the capacitor with at least 5mm clearance around the case to allow convective cooling; forced-air cooling further derates life by ~2x per 10°C reduction in hotspot temperature.
Estimated: Lead-spacing on the AL213639229E3 follows the standard Vishay MAL2136 radial can footprint. Provide at least 2mm clearance from the case to surrounding traces for the insulating blue PET sleeve, and observe the marked polarity stripe on the sleeve for cathode orientation. Wave-soldering the radial leads is preferred; if hand-soldering, limit dwell time to <3 seconds per lead to avoid electrolyte dry-out and pressure-relief vent damage.
Estimated: Do not reverse-bias the AL213639229E3 — the part is polarized and reverse voltage above ~1V can cause dielectric breakdown, gas generation, and pressure-relief venting. Do not apply voltage above 100V DC, even briefly, as this accelerates electrolyte degradation and shortens life. Do not install near heat sources exceeding +105°C, and ensure ripple current stays within the datasheet's published limit at the operating ambient. Failure to observe these limits will void the 4000-hour life guarantee.
