Frequently Asked Questions
What are the key electrical ratings of the Panasonic EEE-1HSR33SR capacitor?
The EEE-1HSR33SR is rated at 0.33 µF capacitance and 50 V working voltage, making it suitable for decoupling and filtering in circuits up to 50 V DC. The VS series construction provides low equivalent series resistance (ESR), supporting efficient energy storage and fast transient response in switching power supply designs.
How does the EEE-1HSR33SR perform in switching power supply output filter circuits compared to standard electrolytic capacitors?
The EEE-1HSR33SR's VS series low-ESR design reduces heat dissipation and improves ripple current handling compared to standard electrolytic capacitors. For a 0.33 µF, 50 V component, lower ESR directly translates to reduced output voltage ripple in buck or boost converters switching at frequencies between 100 kHz and 500 kHz.
Which SMT assembly process is compatible with the EEE-1HSR33SR and what temperature limits apply?
The EEE-1HSR33SR supports standard SMT reflow soldering up to 260°C peak temperature per J-STD-020 guidelines. Its SMD package eliminates the need for wave soldering, enabling fully automated placement in high-volume production runs; the polarized electrolytic construction requires correct polarity orientation during PCB assembly.
For a 5 V rail decoupling network, how many EEE-1HSR33SR capacitors are typically required per power pin?
For a 5 V rail, engineers typically place 1 to 4 EEE-1HSR33SR capacitors (each 0.33 µF at 50 V) per power pin, combining them with 100 nF ceramic capacitors to cover high-frequency noise above 10 MHz. The combination provides effective decoupling from below 1 MHz up to several hundred MHz depending on PCB trace inductance.
