- 105°C rated TG series design provides extended service life at elevated temperatures compared to standard 85°C aluminum electrolytic capacitors
- SMD radial can package enables automated pick-and-place assembly and reflow soldering for high-volume PCB production without through-hole drilling
Applications
The EEE-TG1H330P is used in switching power supply output stages, DC-DC converter bulk capacitor banks, and power management circuits in consumer electronics and industrial equipment where 33 µF at 50 V capacitance is required in a compact SMD footprint. Its 105°C temperature rating makes it suitable for automotive-adjacent electronics, LED drivers, and motor control inverters where ambient temperatures exceed typical 85°C rated capacitor limits. The TG series low-ESR characteristic supports high-frequency ripple current filtering in power factor correction and voltage regulation circuits.

Frequently Asked Questions
What voltage and capacitance ratings does the EEE-TG1H330P offer for power supply filtering?
The EEE-TG1H330P is rated at 33 µF capacitance and 50 V working voltage, making it suitable for output filter capacitors in DC-DC converters operating at bus voltages up to 50 V. This combination provides adequate bulk energy storage for transient load response in 12 V to 48 V power supply designs, and the SMD package allows placement close to load components to minimize parasitic inductance in the power distribution network.
How does the 105°C temperature rating of the EEE-TG1H330P extend service life compared to standard 85°C capacitors?
Electrolytic capacitor lifespan roughly halves for every 10°C rise above rated temperature, following Arrhenius degradation models. The EEE-TG1H330P's 105°C rating means it maintains its rated service life at temperatures 20°C higher than 85°C-rated alternatives. In applications where the ambient temperature reaches 70°C to 85°C near hot components, using a 105°C-rated TG series capacitor can extend operational life by a factor of 4 or more compared to an 85°C-rated 33 µF, 50 V capacitor in the same position.
In which switching power supply topologies is the EEE-TG1H330P most effective as an output capacitor?
The EEE-TG1H330P performs well as an output filter capacitor in buck (step-down), boost (step-up), and flyback converter topologies operating at switching frequencies from 50 kHz to 500 kHz. The 33 µF capacitance reduces output voltage ripple and provides energy storage for load transients, while the low-ESR TG series construction minimizes self-heating from ripple current. It is particularly effective in 12 V output supplies derived from 24 V or 48 V bus rails in industrial control and telecommunications power systems.
What SMD package dimensions should be used when designing a PCB footprint for the EEE-TG1H330P?
The EEE-TG1H330P uses a radial SMD aluminum electrolytic can package. Panasonic's TG series in 33 µF, 50 V is typically available in a 6.3 mm diameter x 7.7 mm height can (D x L dimensions). Designers should use the Panasonic datasheet land pattern for the TG series SMD footprint, as the pad diameter and spacing must accommodate the 6.3 mm base diameter and two bottom-side termination pads with appropriate solder mask clearances for reflow assembly.
