The LS0502SCD33 is a complete solution for a system with a backup storage capacitor or capacitor bank. It integrated input overvoltage, an overcurrent protection circuit, a reverse blocking switch, and a supercapacitor charging control circuit. It also has built-in cell balance to protect two-cell supercapacitor systems. When the main supply is present and above the minimum system supply voltage, the system will draw power from the input supply. At the same time, the integrated linear charger charges the storage element at up to 300 mA current. Once the storage element is charged, the circuit draws only 2.5 μA of current while it maintains the supercapacitor or other storage element in its ready state. When the main supply is removed, the integrated reverse blocking switch will block the current flow from the system rail to the input. The linear charger will be turned on to provide power to the system rail with a low resistance path with up to 2 A current. An integrated cell balancing circuit will keep monitoring the cell voltage when charging and keep the two cells voltage at the same level. The LS0502SCD33 is externally programmable for input current limit, input overvoltage, charge current limit, and charge voltage limit. It provides a flag signal when the input supply is unplugged so that the main system can take action. LS0502SCD33 is available in DFN3X3-10 package.

Green energy and electric transportation systems have pushed explosive growth in inverter markets. Many of these applications present harsh operating environments for power electronics circuitry. Often, these applications demand a high percentage of uptime, increasing the need for highly reliable components. In response, CDE’s BLH series of DC-Link capacitors have been designed and tested to exceed the industry’s most stringent requirements for high humidity, vibration testing, and thermal cycling.
The Temperature, Humidity at Bias (THB) test exposes parts to the harsh conditions of 85 °C at 85% relative humidity with rated voltage applied. This demanding test simulates the harsh operating conditions encountered in many commercial and industrial inverter applications. Such conditions can cause non-THB-rated capacitors to fail early from moisture penetration. While most capacitor makers validate their THB components for 1,000 hours under these conditions, CDE’s BLH series has been validated for 1,500 hours.
Utilizing the most advanced materials and processes, these board-mounted capacitors have been designed and tested to meet the rigors of automotive AEC-Q200 testing. Their solvent-resistant plastic case and epoxy encapsulation system are UL Recognized and meet IEC61071. Tin-plated copper RoHS-compliant terminations ensure excellent solderability. With their superior resistance to moisture and robust design, these capacitors are well suited for solar, wind, UPS, EV chargers, and other inverter applications that may be subjected to wide-ranging environmental conditions.
The series is optimized for DC link applications in medium- to high-power inverters. Capacitance ranges from 1.0 to 170 µF at 450-1,200 Vdc, with high rms ripple current ratings up to 36 Arms. When operated at a 70 °C hotspot temperature with rated voltage applied, their life expectancy is 100,000 hours.
- Optimized for inverter DC-Link Applications
- High capacitance
- High ripple current up to 36 Arms
- Self-healing and low-loss
- THB 85 °C / 85 % RH, 1500h at rated voltage
- UL Listed

THA/THAS Series capacitors are thinner and more cost effective than most alternative technologies. Unlike traditional cylindrical electrolytics, THA/THAS capacitors have sealed, laser-welded aluminum cases to eliminate the need for space-wasting end seal gaskets. Compared to cylindricals, flat THA and THAS capacitors are up to 60% smaller by volume. The design includes a valve to vent hydrogen gas buildups that may otherwise cause pressure-related swelling. The 105°C-rated THAS Series adds a 0.38mm form-fitting stainless-steel sleeve to further prevent swelling at the highest temperatures. Can replace arrays of SMT, radial, or axial aluminum electrolytic and solid tantalum capacitors.
Applications
- Tablets/Laptops
- Specialized instruments
- LED driver modules
- Compact power supplies
- Drones and RPV’s
- Set-top boxes
- Narrow
- 1U rack-mounted devices
- Video monitors
- Solid state drives
- Displays
- Security systems
