Engineers need to fit components into small power supplies. These capacitors help make electronics smaller while keeping performance and safety.
As consumer electronics like laptops, gaming consoles, and chargers become smaller and more powerful, power supply designs face the challenge of fitting reliable components into tighter spaces. Power factor correction (PFC) circuits in these supplies need capacitors that are compact yet robust enough to handle high voltages and demanding operating conditions without failing.
TDK’s B3270xP series of small film capacitors addresses this problem. They are designed for use in power supplies and adapters, specifically in SMPS PFC circuits and low-power electronic device chargers. These capacitors help engineers reduce the size of power supply designs while ensuring stable performance and reliability.
The capacitors support DC voltages up to 450 V and capacitance from 0.47 µF to 2.2 µF. Their low ESR (10 mΩ to 25 mΩ at 100 kHz) helps maintain efficiency, and they can operate at case temperatures up to +110°C. They are built to last, with guaranteed performance over 50,000 hours at +85°C and rated voltage. Their dissipation factor is up to 1.0 ∙ 10⁻³ at 1 kHz.
Available in three versions with different lead spacings, the capacitors feature parallel wire leads and are offered in bulk, ammo pack, or reel formats. They come in halogen-free options and comply with RoHS standards. Their plastic housing and epoxy resin sealing provide flame resistance and mechanical durability. Designers can also use LTspice models to simulate circuit behavior before prototyping.
Power supply designers and electrical engineers working on consumer electronics can use the capacitors. These professionals design power supplies for devices such as laptops, gaming consoles, adapters, and chargers for small electronic gadgets. The capacitors are especially useful for engineers who need to reduce the size of power factor correction (PFC) circuits while maintaining reliability and efficiency. Companies developing compact power supplies for industrial or medical equipment can also benefit from using these capacitors to meet strict safety and performance requirements.
By combining a very compact design, high voltage tolerance, and self-healing properties, these capacitors help power supply designers meet space and reliability demands in modern consumer electronics.
