UCW1H221MNL1GS Product Introduction

UCW1H221MNL1GS is a surface mount aluminum electrolytic capacitor produced by Nichicon, belonging to the UCW series. UCW1H221MNL1GS is an ideal choice for power management, signal coupling and energy storage applications due to its high stability, long life, low impedance and wide temperature adaptability. Whether it is consumer electronics, communication equipment or industrial control, it can provide stable and reliable capacitor solutions and is the preferred component for electronic engineers when designing circuits.

1. Basic parameters

2. Functional characteristics

• High stability and long life
  1. Using high-quality aluminum foil and electrolyte formula, it can still work stably for 7000 hours at a high temperature of 105℃, and its life is far longer than ordinary capacitors.
  2. Wide temperature range (-25℃ to +105℃), adapting to extreme environments, such as industrial control, automotive electronics and other scenarios.
• Low impedance and high ripple current tolerance
  1. ESR as low as 0.35Ω (@20℃/100kHz), reducing circuit loss and improving efficiency.
  2. Ripple current tolerance of 335mA@120Hz or 670mA (typical value), suitable for high-frequency applications such as switching power supplies and motor drives.
• Surface mount compatibility
  1. Radial tubular SMD package (10mm×10mm), supports automated patch production, improves manufacturing efficiency, and reduces manual errors.
  2. Complies with the RoHS directive and lead-free production, suitable for fields with strict environmental protection requirements.
  3. Clear polarity identification (black mark on the top of the shell) to avoid damage caused by installation errors.

3.  Application scenarios

• Power management
  1. Input/output filtering in switching power supplies and linear regulators to reduce voltage ripple and improve power quality.
  2. Stabilize output voltage in chargers and adapters to prevent overcharging and damage to equipment.
• Signal coupling and decoupling
  1. Coupling and decoupling of signal transmission in communication equipment to ensure signal integrity.
  2. Suppressing power supply noise in audio equipment to improve sound quality.
• Energy storage and transient response
  1. Providing energy reserves for scenarios such as motor startup and flashlights that require instantaneous large current discharge.
  2. As a bypass capacitor in digital circuits, it quickly responds to load changes and maintains voltage stability.
• Consumer electronics:
  1. Power management of devices such as smartphones, tablets, and smart watches to extend battery life.
  2. Stabilizing sensor power supply in smart home devices to improve system stability.
• Industrial control and automotive electronics: Voltage stabilization and filtering in industrial automation equipment and automotive electronic control units (ECUs) to adapt to harsh environments such as high temperature and vibration.
