Sulfur resistant design: prevents sulfide corrosion through special processes, suitable for sulfur-containing environments such as chemical and automotive electronics.
Environmental certification: Compliant with EU RoHS and REACH standards.
Price and Supply:
Unit price (5k pieces): approximately ¥ 0.32/piece; The minimum order quantity is 5000 pieces.
Delivery time: Approximately 6 months when inventory is low (shipped in December 2025).
TGL120610F1R30P05Z (Tian Er anti surge resistor)
Features:
Surge resistance: Supports 100V instantaneous high voltage, suitable for power input protection, motor drive and other scenarios.
Low noise design: Metal film structure reduces circuit noise.
Price and Supply:
Unit price (5k pieces): approximately ¥ 0.37/piece; The minimum order quantity is 5000 pieces.
Delivery time: Approximately 4 months (shipped in October 2024).
TRL120610F1R30P05Z (Tian Er Standard Metal Film Resistance)
Features:
Universal design: Balancing cost and performance, suitable for conventional scenarios such as consumer electronics and power conversion.
Process advantages: Metal film evaporation deposition technology, low temperature drift, high stability.
Supply reminder:
The search results did not provide specific prices, but the same series (such as TRL120610FR250P05Z) is a 1/8W model, and the supply status of the 1W version needs to be confirmed.
Other model specifications
EAM/EGM/ELR series:
The search results did not provide specific parameters, and it is speculated that they are similar resistors from other brands (such as Panasonic or Vishay). It is necessary to verify the anti sulfurization/surge capability in conjunction with specific data manuals.
3、 Comparison of key dimensions for selection
|Model | Core advantages | Applicable scenarios | Unit price (5k purchase) | Delivery time|
|TSL120610F1R30P05Z | Corrosion Resistance | Industrial Control, Automotive Electronics | ¥ 0.32 | 6 months|
|TGL120610F1R30P05Z | Anti surge impact | Power protection, motor drive | ¥ 0.37 | 4 months|
|TRL120610F1R30P05Z | High cost-effective universal type | Consumer electronics, ordinary circuits | To be confirmed | To be confirmed|
4、 Selection suggestions
Harsh environment (such as sulfur-containing and high temperature):
→ Prioritize the TSL series (sulfur resistant) to avoid resistance failure due to corrosion.
High wave risk (such as power input terminal):
→ Choose TGL series (anti surge) to enhance system reliability.
Conventional application (cost sensitive design):
Consider the TRL series, but confirm if the 1W version supply and surge/vulcanization meet the requirements.
5、 Procurement precautions
Minimum order quantity: A minimum order of 5000 pieces is required for both Tian'er models.
Delivery time warning: TSL and TGL series have longer delivery times (4-6 months), it is recommended to prepare materials in advance.
Alternative solution: If there is an urgent need for stock, the EAM/EGM/ELR series parameters can be checked, with a focus on comparing the sulfur resistance/surge resistance indicators.
