25D15 SMD NTC Thermistor Small Size No Leads For Electronic Ballasts

Long Life And High Reliability 25D15 NTC Thermal Resistor Strong Ability To Suppress Surge Current
The main advantage
1. Small size, no leads, fast response speed, small space occupied by electronic equipment,
2. Using three-layer electroplating process, it has excellent solderability and solder resistance, suitable for wave soldering and reflow soldering, and suitable for high-speed, high-density surface mount.
Applications:
Can be installed into the power circuits of:
• Power supplies and inverters
• Uninterruptible Power Supplies
• Energy saving lamps
• Electronic Ballasts
• Filament Protection of various types of lamps
• Some types of heaters
• For higher power circuits ask about the MF73
and MF74 series surge suppressors.

Product Process
Precautions for use of NTC thermistor
1. Pay attention to the working temperature of the NTC thermistor.
Do not use NTC thermistors outside the operating temperature range. The operating temperature of φ5, φ7, φ9, φ11 series is -40~+150°C; the operating temperature of φ13, φ15, φ20 series is -40~+200°C.
2. Please pay attention to use NTC thermistor under the condition of rated power.
The maximum rated power of each specification is: φ5-0.7W, φ7-1.2W, φ9-1.9W, φ11-2.3W, φ13-3W, φ15-3.5W, φ20-4W.
3. Precautions for use in high temperature and high humidity environment.
If the thermistor needs to be used in a high-temperature, high-humidity environment, use a sheath-type thermistor, and use a protective sheath to expose the closed part to the environment (water, moisture), and the opening part of the sheath will not directly contact water and steam.
4. Cannot be used in harmful gas and liquid environment.
Do not use it in a corrosive gas environment or an environment where it will be exposed to electrolytes, salt water, acids, alkalis, or organic solvents.
5. Protect the wires.
Do not stretch and bend the wire excessively, and do not apply excessive vibration, shock and pressure.
6. Keep away from heating electronic components.
Avoid installing electronic components that are prone to heat around the power type NTC thermistor. It is recommended to use products with higher leads on the upper part of the bent leg.
