The power range and representative models of 1206 volume patch resistors are as follows:
1、 Power Range
The rated power of 1206 chip resistors is usually 1/4W (0.25W), which is the most common specification and suitable for most conventional circuits. But with special design or material support, its power can be increased to 1W, 2W, or even 3W to meet the requirements of high-power scenarios. For example:
Yuanhui Electronics' 1206 alloy resistor offers three power specifications of 1W, 2W, and 3W, suitable for fields such as new energy batteries and lithium battery protection.
Brands such as TE Con Connectivity and Yageo have also launched 1W high-power models, suitable for scenarios that require higher current resistance.
2、 Representative models
The following are the mainstream 1206 chip resistor models on the market, classified by function:
1. Basic universal type (low-cost, no special protection)
TRL120610FXXP05Z (Day 2)
Power: 1W
Features: Standard metal film resistor, suitable for consumer electronics and ordinary power circuits.
Example models: TRL120610F4R70P05Z (4.7 Ω), TRL120610F9R1P05Z (9.1 Ω).
ELR16FTXXXXDES (Yineng)
Power: 1W
Features: Basic metal film, low cost, suitable for scenarios with low protection requirements.
Example models: ELR16FT5R1DES (5.1 Ω), ELR16FT9R1DES (9.1 Ω).
2. Surge resistant type (resistant to instantaneous high current impact)

Power: 1W
Features: Anti surge design, able to withstand 15-20 A/10 μ s pulses, certified by AEC-Q200 automotive standards, suitable for automotive OBC and industrial frequency converters.
Example models: EGM16FT4R7DES (4.7 Ω), EGM16FT7R5DES (7.5 Ω).
3. Sulfur resistant (corrosion-resistant, suitable for sulfur-containing environments)
TSL120610FXP05Z (Day 2)
Power: 1W
Features: The surface passivation layer blocks sulfide corrosion and is suitable for chemical sensors and automotive fuel systems.
Example models: TSL120610F5R6P05Z (5.6 Ω), TSL120610F8R2P05Z (8.2 Ω).
EAM16FTXXXDES (Billion Energy)
Power: 1W
Features: Multi layer passivation process, resistant to sulfide corrosion, suitable for industrial equipment and automotive electronics.
Example models: EAM16FT6R2DES (6.2 Ω), EAM16FT9R1DES (9.1 Ω).
3、 Selection suggestions
Conventional scenario (low-cost priority):
Choose TRL120610FXXXP05Z (Tian Er) or ELR16FTXDXES (Yi Neng) to meet basic needs with the lowest cost.
Surge resistance requirements (such as power filtering, motor control):
TGL120610FXXP05Z (Tian'er) is preferred for its strong surge resistance; If vehicle certification is required, choose EGM16FTXXXDES.
High sulfur/corrosive environments (such as chemical and automotive fuel systems):
Choose TSL120610FXXP05Z (Tian Er) or EAM16FTXXXDES (Yi Neng) for sulfur resistant design to extend lifespan.
High power scenarios (such as new energy battery management):
Consider Yuanhui Electronics' 1206 alloy resistor (2W/3W) to provide higher power density.
4、 Precautions
Minimum order quantity and delivery time: For most models, the minimum order quantity is ≥ 5000 pieces and the delivery time is 4-10 weeks. Inventory planning is required in advance.
Heat dissipation design: A 1W power is considered a high load in the 1206 package. It is recommended to reserve heat dissipation copper foil on the PCB (such as thickening the electrode design to reduce temperature rise by 28 ℃).
Actual testing and verification: Before bulk procurement, it is necessary to request samples to test the temperature drift and surge tolerance under actual working conditions.
Select the corresponding model based on specific application scenarios, and prioritize contacting suppliers to confirm inventory and parameter details. If further cost or performance optimization is needed, alternative solutions (such as the Tian Er TSL series anti sulfurization resistors) can be considered.
